Camera Properties

Cameras can be configured according to the properties of the real- world cameras they represent.

To create a camera and amend canera properties:

1. Open the stage editor by right clicking stage from the dashboard or by right-clicking the floor in the visualiser.
2. Expand the Cameras tab.
3. Right-click a camera from the list or create a new one.
4. Adjust the desired properties of the camera using the editor.

Settings

Offset

The offset in meters of the camera’s position from its parent. When parented to the stage which is the default this is the camera’s world position.

Rotation

The rotation transformation in degrees from its parent. When parented to the stage, which is the default, this is the camera’s world rotation.####

Tracking source

See Object tracking source for more information.

Resolution Source ( visualiser camera only)

• Take from GUI - Default, Use the resolution of the GUI display.
• Fixed - You can specify a custom resolution. Will not change the resolution of the display, only the camera’s view.

Resolution

The resolution that the camera will use to render its view.

Field of view (vertical)

The vertical field of view in degrees of the camera.

Field of view (horizontal)

The horizontal field of view in degrees of the camera.

Preview

Camera plate

Sets the camera to Transmission, Backplate or Frontplate.

Show Alpha

Toggles whether the camera will show Alpha or not.

Output

Set extension fade

Opacity of the set extension.

Set extension feather

Feather of the set extension. This is defined as the width of the feather.

Video input fade

Defines whether you have video input on or off. Helpful if you want to see how well the set extension is lined up.

AR fade

AR content on or off. Frontplate content only. Helpful to see how well the AR content is lined up.

Radial mask scale

Applies a radial mask to the film content.

Frontplate reprojection

• Backplate aligned

Front plate is delayed and reprojected with the backplate so frontplate and backplate content are displayed in sync. This is the default.

• No reprojection

Frontplate is delayed along with the backplate content but is not reprojected. This is used for frontplate content that aligns more with the filmed content.

• Minimal latency

Backplate image and frontplate images are taken from two different points in time. This results in the latest frontpate frame being displayed.

Frontplate composite order

Defines how content assigned to frontplate is ordered in the composite stack.

Colour LUT

Defines which LUT is applied to the camera. Designer has a number of LUT files built in.

Colour profile

Defines which colour profile the camera is. Designer has a number of colour profiles built in.

Hold output

Hold output freezes the current frame of the camera output. This is a toggle setting.

Stage Render

Render Settings

Multiple render setting configurations can be created for each camera.

Right click on Default to open the Default configuration; left click on Default to open the StageRenderSettings list manager to create a new configuration or recall an existing one.

Render settings can be configured for these properties:

Virtual Object Alpha

Opacity of virtual objects in render layers other than onstage or offstage

Label Visibility

Projector Labels

Labels for projectors only.

Projection Surface Labels

Labels for projection surfaces only.

LED Screen labels

Labels for LED screens only.

DMX Screen Labels

Labels for DMX Screens only.

DMX Light Labels

Labels for DMX Fixtures only.

Prop Labels

Labels for props only.

Camera Labels

Labels for cameras.

Tracked Point Labels

Labels for tracked points only.

Reference Point Labels

Labels for reference points only.

Renderer

• Renderer
• Light
• White Point
• Ambient Occlusion
• Glow Brightness
• Background colour
• Anti-aliasing

Renderer

• Schematic - Uses the Schematic renderer.
• Lux - Uses the Lux renderer.
• Heatmap - Uses the Heatmap renderer.

Light (only available for Heatmap)

• Luminance - Luminance - The intensity of light emitting from an object or surface per meter in a given direction, measured in nits (cd/m²)
• Illuminance - The density of incident light in lumens hitting a surface per meter, measured in lux (lm/m²).

White point

Camera exposure in lux.

Ambient occlusion power

Power of the ambient occlusion effect in the lux renderer. 0 disables it.

Glow brightness

Impact of glow effect in lux renderer.

Background colour

Changes the background colour of the scene. In schematic this will be the background colour.

In Lux this will be the base colour of the environment and is affected by lighting. For example if the ambient light is 0 the background will be black regardless of the colour.

In heatmaps the background is always black.

Anti-aliasing

Anti aliasing can smooth out jagged edges caused by aliasing. The higher the number the smoother aliasing, but at more of a performance cost.

Face Cull Mode

Used to temporarily disable rendering of faces with normals pointing to the front or to the back

Stage Render > Camera type

• Perspective - Perspective view.
• Orthographic - Orthographic view.

Orthographic scale

Orthographic Camera has no concept of depth and distance from the scene. A zoom-like effect can be achieved by adjusting the Orthographic Scale, but this setting is independent from Zoom in the equivalent Perspective Camera.

Near & Far clipping plane

Any geometry closer than the near clipping plane or further than the far clipping plane will clipped (not be rendered). The values are in meters.

Reducing the range of these values can improve shadow quality and reduce shadow acne.

Physical

Video in

Defines the live video input this camera is linked to.

Live action position marker

Used as a reference to re-align filmed content when using virtual zoom.

Spatial calibration

Used to create spatial calibration configurations

Video receive delay (sec)

Roundtrip latency time calculated from calibration process.

Spatial Tracker delay (sec)

Amount of time in seconds between the camera frame arriving and the tracking data associated with it arriving. This is calibrated automatically.

Lens Tracker delay (sec)

Allows for adjustment to the time needed to sync between lens and tracking data.

Lens

Overscan

Defines the overscan ratio. Default is 1. Setting to 1.1 would mean an overscan of 10%. The higher the overscan, the higher the performance impact.

Overscan resolution

Overscan resolution is the readout value in resolution of the overscan values.

Aspect ratio

This is a readout value of the final aspect ratio of the camera.

Focal length

This is a readout value of the calculated focal length of the camera.

Sensor width

Defines the sensor width.

Centre shift

Offset of the focal point of the lens from the centre of the light sensor, measured in mm.

K1, K2, K3

• k1 - First order radial distortion coefficient, as measured.
• k2 - Second order radial distortion coefficient, as measured. = k3 - Third order radial distortion coefficient, as measured.

Prediction

Camera imaging delay (sec)

The amount of time between Designer outputting the frame and capturing the image. Prediction is turned off when this value is zero. If you want to turn prediction on, increase this value until the image looks good. Do not increase beyond the Video Receive Delay value.

Camera imaging delay prediction samples

How much of the history of the tracking data to predict into the future. Expressed in frames.

Camera imaging delay prediction terms

How many terms we used to model the movement. Two terms is linear. Three terms is a cubic prediction.

Hierarchy

Parent

Shows the parent object (this is usually the stage, so the object will be offset from the origin point of the stage).

Children

Shows children of the object.

• Click Add child to create a parent/child relationship between this object and another.
• Click Parent to stage to re-parent the object back to the stages origin point.
